The Best Rockhounding Sites in Hawaii
One of the only green sand beaches on Earth, documented for olivine and gem peridot — the sand itself is olivine crystal, eroded from a cinder cone and concentrated by the surf into a green crescent at South Point. Come to see it, photograph it, and let it be: removing sand is prohibited, and the hike in is the reward.
The Wai’anae Range pass documented for clear and yellow labradorite — glassy feldspar crystals weathering from the old volcano’s basalt. It is the closest thing O’ahu has to a classic mineral locality. Access crosses a patchwork of private and state land, so confirm permissions before hunting the road cuts and washes.
Hawai’i’s best-known mineral site, documented for analcime, chabazite, and quartz lining gas pockets in the Ko’olau basalt — sharp little zeolite crystals that put O’ahu in collections worldwide. The quarry is private ground: permission first, always, and club connections are the realistic way in.
The windward side’s documented quartz and jasper ground, mapped as north and south areas around Kailua. Weathered Ko’olau basalt sheds chalcedony, quartz, and red-brown jasper into gulches and road cuts — modest material by mainland standards, but honest island rockhounding minutes from the beach.
Lana’i’s documented sunstone locality: golden feldspar with a warm schiller, weathering from the basalt above the island’s resort bay. Sharp eyes find small flashing grains in the washes and shoreline gravel. Most of Lana’i is privately held — stay on public shoreline and established trails.
The central O’ahu plateau, documented for jasper — deep red and mustard stones weathered from the old lava flows between the two mountain ranges. Gulches and washed red-dirt ground around town produce tumbling-grade pieces. Respect the patchwork of agricultural and military land that surrounds the town.
A documented quartz locality in a deep West Maui valley — chalcedony and quartz weathering from the old caldera complex upstream. Olowalu is also home to some of Hawai’i’s most important petroglyphs: cultural sites are strictly protected, so admire the pu’u honua and keep any hunting to the open streambed.
Rockhounding Regions of Hawaii
| Region | Top sites | What you'll find |
|---|---|---|
| Windward O’ahu | Kailua North, Kailua South, Kapa’a Quarry | Quartz and jasper in the Ko’olau basalt, with analcime and chabazite zeolites at the famous quarry — private, permission first |
| Central O’ahu and the Wai’anae Range | Pohakea Pass, Wahiawa | Clear and yellow labradorite crystals at the pass, red jasper in the Wahiawa gulches |
| Big Island south point | Papakolea Green Sand Beach | Olivine and gem peridot — one of the only green sand beaches on Earth, protected: look, don’t take |
| Maui | Haleakala National Park, Olowalu Valley | Augite crystals in the crater country — observation only inside the park — and quartz in the Olowalu Valley |
| Lana’i | Manele Bay | Documented sunstone feldspar on the island’s south shore |

Best Time for Crystal Hunting in Hawaii
Hawai’i is a year-round destination — the collecting calendar is really a weather calendar. Winter swells rework the beaches and winter rains flush the gulches; the leeward sites (Pohakea Pass, Wahiawa, Olowalu) stay drier and hunt best after a storm passes through.
Set expectations honestly: Hawai’i is the observation state. National parks, state parks, conservation districts, and Hawaiian Home Lands cover most wild ground, and removal is prohibited on nearly all of it. The islands offer the best real-time geology in America — active volcanism at Kilauea, the Bishop Museum’s mineral collection in Honolulu — and that, not a full bucket, is the trip.
Where collecting is possible, it runs on permission and respect: Kapa’a Quarry is private ground, Pohakea Pass crosses mixed ownership, and archaeological sites — heiau, fishponds, petroglyphs — are protected everywhere under state and federal law. Hawaiian cultural practice regards the rock as Pele’s; thousands of visitors mail “borrowed” lava stones back every year. Leave it where it lies.
Check current weather and road conditions before heading out, especially for remote BLM and Forest Service roads.
Where to Find Olivine (Peridot) in Hawaii
Hawaii is built entirely from basaltic lava, and olivine (the gem variety is peridot) is one of the primary minerals in Hawaiian basalt. Green olivine crystals are found as loose grains in beach sand and as xenoliths (chunks of mantle rock) carried to the surface in erupted lava. Papakolea Beach on the Big Island is one of only four green sand beaches in the world.
Top sites:
- Papakolea (Green Sand Beach), Big Island — Olivine-rich beach at the base of the Pu'u Mahana cinder cone. The green sand is olivine grains eroded from the cone. Note: Removing sand from the beach is prohibited — this is Hawaiian Home Lands and considered sacred. Look, do not collect.
- Diamond Head, Oahu — Olivine crystals in the tuff walls of the crater. Collecting inside Diamond Head State Monument is prohibited, but understanding the geology is worthwhile.
Olivine is a glassy green mineral, hardness 6.5-7. In Hawaiian basalt, it appears as small green crystals or grains embedded in dark gray or black rock. Larger crystals (gem-quality peridot) are uncommon. Hawaiian cultural practices consider removing rocks from the islands disrespectful — many visitors choose not to collect out of respect for the host culture.
Where to Find Volcanic Glass (Pele's Tears) in Hawaii
Hawaii produces volcanic glass in several forms. Pele's tears are droplets of basaltic glass formed when lava fountains cool rapidly in the air. Pele's hair consists of thin glass fibers — stretched lava strands. Both are found downwind of active or recently active vents. Obsidian (in the continental sense — rhyolitic glass) does not occur in Hawaii because the lava is basaltic, not silicic.
Where found:
- Kilauea, Big Island — Pele's tears and Pele's hair near recent eruption sites. Hawaii Volcanoes National Park prohibits collecting. Adjacent private land may have specimens — ask permission.
Pele's tears are small (pea-sized), glassy black droplets, often with a teardrop or spherical shape. Pele's hair is golden-brown glass fiber. Both are culturally significant to Native Hawaiians. Collecting anything from Hawaii Volcanoes National Park is a federal offense. The cultural tradition also holds that removing volcanic rock from Hawaii brings bad luck — the park receives packages of returned rocks regularly.
Where to Find Zeolites in Hawaii
Zeolite minerals form in the vesicles (gas bubbles) of weathered Hawaiian basalt. Chabazite, phillipsite, and analcime are the most common species. They form as groundwater percolates through the porous basalt and deposits silicate minerals in the voids.
Where found:
- Waianae Range, Oahu — Zeolites in weathered basalt road cuts. Some areas are on private or military land — verify access.
- Table Mountain area, Oahu — Zeolite-bearing basalt. Road cut exposures.
Zeolites in Hawaii are small — typically millimeter-scale crystals in vesicles. A hand lens or loupe is necessary for identification. They are white to colorless and often associated with calcite and clay minerals. Collecting opportunities in Hawaii are limited by land ownership (most land is private, military, or state/federal parkland). Always verify access rights before collecting.
Hawaii Rockhounding Laws & Public Land Rules
BLM Land
Hawaii has no BLM land.
National Forests
Hawaii has no National Forest land.
State Parks
Collecting is prohibited in all Hawaii state parks, including Diamond Head State Monument. Hawaii Volcanoes National Park (federal) strictly prohibits removing any rocks, sand, or plant material.
Collection Limits
No federal or state land is available for recreational mineral collecting in Hawaii.
What's Protected
Virtually all natural areas in Hawaii are protected. Hawaiian Home Lands, conservation districts, forest reserves, and National Parks cover the majority of undeveloped land. All archaeological sites (heiau, fishponds, petroglyph fields) are protected under both state and federal law.
Hawaii is primarily a geology observation and education destination, not a collecting destination. The best use of a rockhounding trip to Hawaii is studying active volcanism at Kilauea, visiting the Bishop Museum mineral collection in Honolulu, and observing geological processes in real time. Respect Hawaiian cultural practices regarding the removal of natural materials from the islands.

Gear Checklist for Rock Hunting & Gem Mining in Hawaii
What you need depends on the terrain and what you are collecting. Here is a general checklist for Hawaii:
- Rock hammer (3 lb crack hammer for hard rock, geologist's pick for softer material)
- Safety glasses — required any time you swing a hammer
- Chisels — cold chisels for splitting seams and extracting crystals
- Bucket and bags — 5-gallon bucket, zip-lock bags for specimens
- GPS device or phone app — cell service is unreliable at most sites
- 1 gallon of water per person — minimum, more in summer
- Sturdy boots — ankle support for loose talus and mine tailings
- Field guide — a regional mineral identification guide for Hawaii
Always respect private property, follow Leave No Trace principles, and check current regulations before collecting. On BLM land, the general rule is 25 lbs per day plus one specimen for personal, non-commercial use.

What gemstones are found in Hawaii?
The state gem is black coral — a marine gem, commercially harvested, not beach-picked. On land, the documented finds are volcanic: gem peridot and olivine at Papakolea Green Sand Beach, sunstone at Manele Bay on Lana’i, clear and yellow labradorite at Pohakea Pass, and quartz and jasper across O’ahu and Maui. Zeolite crystals from Kapa’a Quarry are the specimen prize. Note that most sites are look-only or permission-first — Hawai’i protects nearly all of its wild ground.
Is there gold in Hawaii? What about diamonds?
Honest answer: no to both. Gold and diamonds need ancient continental rock — deep veins, eroding mountains, volcanic pipes — and the Hawaiian islands are young oceanic basalt with none of it. There is no placer gold in the streams and no diamond source in the ground. Diamond Head itself is the tell: British sailors named it for glittering calcite crystals they mistook for diamonds. The real Hawaiian gems are peridot, sunstone, and black coral.
Can you take rocks from Hawaii?
Mostly no. Hawai’i Volcanoes National Park and Haleakala prohibit removing any rock, sand, or plant material; state parks — Diamond Head included — prohibit collecting; and conservation districts, forest reserves, and Hawaiian Home Lands cover most of the rest. Papakolea’s green sand is protected. Beyond the law, Hawaiian cultural practice asks that Pele’s rock stay where it lies — parks receive boxes of returned stones every year from visitors who regretted the souvenir.
Is there a Hawaii rockhounding map?
Yes — the interactive map above shows 10 documented Hawai’i locations, filterable by mineral and access type, 9 of them public-access or permission-based sites. It is the smallest state list on the site and honestly framed: Hawai’i is a geology-observation destination first, with documented minerals at Papakolea, Pohakea Pass, Kapa’a Quarry, and a handful of island localities. Check access rules on every site before you go — protection is the rule here, not the exception.
